1993 90 front radius arm bush lengths?

[lynall]

Does anyone know the difference in length between early and later front radius arm bushes?
Weirdly google seems very secretive on this point.

I have the part numbers NTC7307 up to 94 and chassis number KA, and NTC6781 94 onwards and chassis number LA onwards, now mine is chassis number LA onwards but is a 1993 car!

Any help much appreciated.

Thank you, that is exactly the info I am after.
Adverts for the bushes mention early narrow arms, so assuming narrow arms match to narrow bushes!

Thought they were the same length. It’s the bush size on the C ends that differ.
Changed sizes between 200 300.
Early narrow
Later large
Used to be able to tell the size change by a little triangle on top or the arm.

Are the top hat rubbers the same???
I just had a thought . Holes in chassis are same size it’s the thread size that may be smaller on earlier ones

I have no idea, one of the C bushes has been shedded for years now, and as I am replacing rear radius arms as they are rot, I thought I would treat the old girl and do the lot whilst over the pit.

Front radius arms width

Ive searched and managed to find out theres two widths of radius arm/bush 50/54mm, what i cant find out is there any difference to the arm at the chassis end? Reason i ask as my radius arm bolts keep working loose, after finding out the bush width info i measured mine to find its a 54mm wide...

Am getting old as cannot even remember doing that!
The other thing is I cannot remember is did I fit washers or replacement arms?

Thinking back (dangerous) I was looking for castor corrected bushes & the sizes were listed, a quick google might bring somit
up.

Another thing I was swapping axles as I bought two rebuilt axles with diff locks & radius arms iirc the front axle was wider
& didnt fit unless I fitted washers. They came off a 110 just to make things worse.

I will have fun when I swap the ones over on the son's Ninety, narrow arms and a Disco 1 axle which have wide arms. Must have spacers or the mounts have been adjusted to fit the arms.

I replaced a front axle on a mates truck for one from a Disco and just used spacers. Simple way is just to get the wider arms with the replacement axle if you can.

Could be a defender casing to allow the wide arms, same as my modded 109 with vented discs.

I find it very strange they didn't do that, the engine and axle are mostl likely out of the same vehicle, would have made sense to use the relevant arms.
Mind you I haven't measured them, I was going by the fact it has the little raised triangle on the arms that the narrow ones have.

Finally remembered to crawl underneath and have a measure, axles are 54mm bush lengths and arms are 50mm bush length, bolts tightened until lugs bend inwards and touched the bush boss, not sure if that was my skulldduggery but I suspect it was!
New bush kits ordered for early arms, and this time will shim with washers!

Only yesterday I could not get a piston out of no6 cylinder bore as I had not realised there was an anti polishing ring in the top of the liner, which made the piston jam up, so I had to stick a bar up from underneath and bottle jack the piston and liner out as one I was watching as the truck chassis started to lift and the liner crept up knatts cock at a time, until whoosh I got a coolant shower!
One snapped piston ring caused all this work, head gasket a bit skanky as well.
